Abstract
A combined cartridge fuse holder and switch employs a novel switching mechanism including a pair of spaced bars arranged in a first plane and positioned adjacent an inclined ramp. A contact pin is mounted in a switch arm, which in turn is pivotally mounted so that the pin can be moved from an OFF position in which the pin rests on the inclined ramp to an ON position resting on and bridging the contact bars. One of the contact bars is electrically coupled to a first terminal while the other of the contact bars is electrically coupled through a fuse to a second terminal.
Claims14
A combination cartridge fuse holder and switch comprising:
- a first contact bar and a second contact bar having upper edges, and having first ends,
- a first terminal and a second terminal,
- body means defining a cartridge fuse receptacle and a pair of contact bar receiving means, said contact bar receiving means being spaced and constructed to receive said first and second contact bars so that the upper edges are spaced from each other and so that the upper edges lie substantially in a contact plane, said body means further defining a ramp inclined relative to said contact plane and intersecting said contact plane adjacent the first ends of said contact bars, said first and second terminals being mounted on said body means,
- first connecting means for placing said first contact bar in electrical connection with said first terminal,
- second connecting means for placing said second contact bar in electrical connection with one end of said fuse receptacle so that when a cartridge fuse is positioned in said receptacle, one end of said fuse is in electrical contact with said second contact bar,
- third connecting means for placing said second terminal in electrical connection with the other end of said fuse receptacle so that when a cartridge fuse is positioned in said receptacle, the other end of said fuse is in electrical contact with said second terminal, and
- a contact pin, and holder means associated with the body means for moving said contact pin from said ramp on and off the upper edges of said contact bars to make and break contact between said first and second terminals when a cartridge fuse is positioned in said fuse receptacle.
